We have proposed novel Head Mounted Display (HMD) pancake optics named “Double path” pancake optics to achieve both compactness and high light efficiency simultaneously. We made the prototype with 25.5 mm thickness of optics and confirmed high image quality with 1.8 times higher light efficiency compared to that of conventional one.
